Adoption of the hybrid rice varieties by farmers is often impaired by the high price of hybrid seed, due to low yields in hybrid seed production fields. Female outcrossing ability and female hybrid seed production ability, defined as the rate of filled spikelets of the male sterile line and as its grain yield under outcrossing, respectively, determine plant traits for hybrid seed yield. We identified an morphological characters and outcrossing rate ability of 6 hybrid rice combination that affect grain yield of hybrid rice seed production. The experiment conducted in 3 locations i.e. Subang, Malang, and Ungaran districts during dry season of 2016. Subang is the best location to hybrid rice seed production with the highest average of grain yield. Hipa 19 was the hybrid varieties having > 1 ton/ha grain yield highest that others. The important agronomic characteristics that affected of F1 grain yield i.e. plant height, number productive tillers, number of filled grains, exerted panicle rate, dan outcrossing rate. Correlations between number of filled grains, outcrossing rate, and grain yield were tight and highly significant. High yield potential and cost-effective for hybrid seed production can be achieved using hybrid rice with high outcrossing rate and suitable condition of an environment.

East Java Province supplies one third of the national peanut production. The farmland of peanut production centers in the region is a coastal area prone to salinity. The use of variety adaptive to salinity stress is an effective strategy to cope sainity problem and to optimize the use of salt-affected land. The aim of the research was to evaluate the adaptability of peanut varieties to salinity stress.The research was conducted in the 2018 dry season in the saline paddy field in Gesikharjo Village, Palang Sub District, Tuban Regency with EC 14.54 dS/m. The treatments consisted of seven groundnut varieties (Singa, Singa, Kancil, Takar 2, Bison, Hypoma 2, Tuban, and Jerapah), using a randomized complete design, four replications. Observations consisted of growth parameters, yield and yield components, proline and macro nutrient (N, P, K) content. The results showed that high salinity stress reduced seed germination, plant growth, yield components and yields of all varieties tested. Based on the ability to survive and yield, Singa variety have showing higher tolerance to salinity stress or more adaptive than other varieties, while the lowest one was found in Jerapah variety. The salinity tolerance of Singa variety did not indicate to be associated with high proline content, but it seem more related to the ability to absorb higher N, and keep K high to reduce negative effect of Na.

Multi-environment experiment could reveal the performance and adaptation of the advanced breeding lines for specific or general environment. The objective of the present investigation was to analyze the pattern of Genotype x Environment (G x E) interaction for grain yield of 67 genotypes by Additive Main effects and Multiplicative Interaction (AMMI) model using the data generated from observational yield trial in three different coastal rice environment in Indonesia including one site in coastal of Eretan, Indramayu (West Java) and two sites in the coastal area of Mataram, West Nusatenggara during dry season of 2009. In each location, the experiment was arranged in a randomized complete block design with three replications, 5m2 plot size and 20 cm x 20 cm of planting space. Standard management practices for irrigation field were followed for all trials. The results showed the highly significant genotypic and G x E interaction. The genotype x environment (GxE) interaction influenced the relative ranking of the genotypes across environment. Genotype 62(IR76397-2B-6-1-1-1-1), G3(IR58427-5B-15), G61(IR76393-2B-7-1-1-3-1), G19 (IR73055-8-1-1-3-1), G26 (IR 77674-3B-8-2-2-14-1-AJY5), G38(IR77674-3B-8-2-2-14-2-AJY4), G35(IR77674-3B-8-1-3-13-2-AJY2), G44(IR68144-2B-2-2-3-3), and G53(IR72593-B-18-2-2-2) produced higher yield compared to the overall mean, and showed low G x E interaction effect with low ASV (AMMIâ€™s Stability Value) score presented the high yield genotype with high adaptability compared to the checks. G23(IR77674-B-20-1-2-1-3-6-4-AJY1,8.39 t/ha), G25 (IR 77674-3B-8-2-2-12-5-AJY2, 8.11 t/ha), G24(IR77674-3B-8-2-2-8-3-AJY4, 8.32 t/ha), G18(IR72049-B-R-22-3-1-1, 8.78 t/ha), produced high yield and indicated suitable for Eretan environment. Both the stable genotypes and the specific adaptation genotypes with the highest average yield compared to the checks will be further evaluated in prelimenary yieid trials in the several environments with the bigger size plot.

Peningkatan produksi kedelai nasional dapat diupayakan melalui intensifikasi pada lahan optimal, dan perluasan area tanam pada lahan-lahan suboptimal diantaranya lahan kering iklim kering (LKIK). Salah satu upaya peningkatan produktivitas di LKIK adalah dengan penerapan pola tanam tumpangsari. Penelitian bertujuan untuk mengetahui keunggulan ekonomis dan penerimaan petani terhadap introduksi paket teknologi tumpangsari kedelai dengan jagung di sentra produksi jagung pada LKIK Kabupaten Tuban, Jawa Timur. Penelitian dilaksanakan pada musim tanam Maret-Juli 2019 di Desa Pongpongan Kecamatan Merakurak, dan Desa Gesing Kecamatan Semanding. Parameter yang diamati meliputi keragaan hasil biji kedelai dan jagung, biaya produksi, penerimaan, dan keuntungan usahatani, keunggulan ekonomis pola tanam tumpangsari (R/C rasio, B/C rasio, IKF, dan NKP), dan penerimaan petani. Paket teknologi tumpangsari kedelai dengan jagung, yakni jagung ditanam baris ganda (40 cm x 20 cm) x 200 cm satu tanaman/lubang dan kedelai diantara baris ganda jagung dengan jarak tanam 30 cm x15 cm dua tanaman/lubang (isi 5 baris kedelai), dosis pupuk sesuai kesuburan tanah dan populasi tanaman mampu memberikan keuntungan lebih tinggi dibandingkan pola tanam monokultur jagung. Hal ini karena hasil jagung pada pola tanam tumpangsari juga relatif sama dengan hasil jagung pola tanam monokultur. Tumpangsari kedelai varietas Dena 1 dengan jagung memiliki keunggulan ekonomis lebih tinggi dibandingkan tumpangsari jagung dengan varietas kedelai lainnya, dengan keuntungan Rp 19.146.500/ha; R/C rasio 2,51; B/C rasio 1,51; IKF 12.843; dan NKP 1,69. Petani tertarik untuk mengadopsi paket teknologi tumpangsari ini apabila hasil yang didapatkan lebih menguntungkan dibandingkan pola tanam monokultur jagung yang selama ini diterapkan oleh petani.Kata kunci: lahan kering iklim kering, keunggulan ekonomis, tumpangsari kedelai dengan jagung

Seed quality testing is one of aspect control and quality assurance for certified seeds. The grain shape is one of the important parameter components tested in the seed certification process especially in the field. The common method used were using human/ analysts visual observation. It has a high degree of subjectivity and low efficiency. Observation of complex samples in the field requires an alternative observation that is more subjective and accurate. An alternative technology for identifying seeds during certification and production is identification based on digital images. The purpose of this study were to identify and classify rice seeds based on physical form using digital image analysis. A total of 20 varieties with various shapes have been taken with a microscope that connected to the camera and computer. The resulting image file was analyzed using imageJ 1.51k software and analyzed statistic to discriminate the seeds tested according to their group. Results from this study indicated that digital image analysis is able to identify and classify seeds. The grouping of seeds into long, medium and round seed categories based on perimeter, circularity, AR, and round parameters with successive correlation levels is 95.4%; 82.5%; 45.3% and 38.9%. This method is more sensitive to identifying seed characteristics than eye visualization of seeds whose physical size is outside the range of numbers specified in the description. For example Cisadane, Gilirang and Ketonggo seeds.
